ATTACHMENT FOR STOVES.

Application led December 20, 1919. Serial No. 346,286.

To all ll1/tom t may concern.'

Be it known that I, RONALD ELIsoN CAMPBELL, a citizen of the United States, and residing at Columbia, Richland County, State of South Carolina, have invented certain new and useful Improvements in Attachments for Stoves, of which the following is a specification.

The object of the present invention is to provide an attachment for stoves by means of which the common sheet metal wood burning stove or trash burner can be quickly and conveniently converted into a coal burning stove without making alterations in the stove itself. The attachment comprises es# sentially a cast iron grate which is adapted to be inserted into the combustion chamber of a sheet metal stove, and to be suspended therein out of contact with the walls, by means of a special suspending device comprising a substantially horizontally disposed adjustable bar, the ends of which are supported by the stove body, and a plurality of suspending rods connecting the grate and bar. The invention is particularly applicable to the type of sheet metal stove having a fuel opening inthe top through which the grate may be conveniently inserted and withdrawn, the edges of the opening being reinforced with metal plates and serving as supports for the ends of the bar from which the grate is suspended.

One form of the invention will be disclosed in the following description taken in connection with the accompanying drawings, in which- Fig. 1 is a section through a common form of sheet metal stove, showing the grate suspended therein;

Fig. 2 is a sectional view through the upper portion of the stove, taken at right angles to the section shown in Figure 1;

Figs. 3 and L1 are two views of a detail.

The sheet metal body of a common wood burning .or trash burning stove is indicated at l0 in the drawings, the body being mounted upon suitable legs and having a circular fuel opening 11 in the top. This fuel opening is normally closed by a cover 12. Suspended within the combustion chamber of the stove is a cast iron grate 13, which is cylindrical in shape and somewhat smaller in diameter than the opening 11 in the top of the stove. This grate 13 is supported out of contact with the walls and bottom of the stove preferably by suspending it from the top, as shown in Figure 1.

The suspending means comprises essentially an extensible bar B having two parallel portions B and B2, which are held together in proper relative position by means of a clamping dev'ice C. This clamping device is clearly shown in Figures 3 and 4, and consists essentially in two plates C and C2, which may be drawn together by rotatlng the thumb nut C3 on the bolt C4, to tightly clamp the two members of the cross bar. To the outer ends of members B and B2 respectively, are secured plates 111 and 15, each of which is formed with an outwardly extending flange at its upper edge which fits over the edge 'of the annular flange surrounding the opening 11 in the stove.

The grate 13 is connected to the bar B by means of suspension rods 16, which may be provided with hooks at their tops extending around the bar B and hooks attheir lower ends engaging the upper portion of the grate. This form of grate supporting means may be used in all cases where the stove or trash burner has a considerable opening in its top through which the grate may be introduced and withdrawn, and the adjustable bar renders it applicable to stoves having different sized openings. By merely changing the length of the bar B, the grate may be suspended in a stove having a considerably larger fuel opening than the opening in the stove illustrated.

y means of my attachment described above, I can convert the common, cheap sheet metal wood or trash burning stove into a coal burning stove quickly and conveniently and without making any change in the stove itself. In this manner I realize at small additional cost the advantages of both the wood and coal burning stoves, being able to use the stove as a wood burner or trash burner when desired to make a hot fire in a short time, or to use the stove as a coal burner when it is desired to have a long continued fire of less intensity. It is obvious from` the above description that changes may be made in the design and arrangement of the features of my invention and I do not, therefore limit myself to the exact form shown and described.

I-Iaving thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

An attachment for stoves, comprising a grate adapted to be inserted within the body 5 of a stove, and means for supporting the same out of Contact with the walls of the stove, said means including a bar comprising two portions relatively movable longitudinally and a member for clamping said portions in any desired relative position, said bar being adapted to be supported at its ends by the stove7 and suspending rods connecting said bar and grate, Jfor the purpose set forth.

In testimony whereof I affix my signature.

RONALD ELISON CAMPBELL.
